Areas affected...portions of western Nebraska and far northeastern
Colorado

Concerning...Severe potential...Watch unlikely=20

Valid 080215Z - 080315Z

Probability of Watch Issuance...20 percent

SUMMARY...A cluster of storms may produce a few severe gusts and
large hail this evening across portions of western Nebraska and far northeastern Colorado. A watch is not likely at this time.

DISCUSSION...Storms are ongoing across western Nebraska this evening
south of a mid-level jet and associated surface low, situated across southwestern South Dakota. The 00Z LBF RAOB showed generally weak
winds through the depth of the column but generally steep lapse
rates. Relatively low boundary-layer relative humidity may
contribute to a threat for severe gusts, and the steep lapse rates
may result in a threat for large hail, though modest deep-layer
shear may limit this threat. Storm coverage should generally decline
with loss of diurnal heating and associated increase in inhibition.
However, moist south-southeasterlies and the development of a
low-level jet with boundary-layer decoupling may allow the cluster
of storms to persist for a couple hours after sunset. Due to the
short duration and localized nature of this threat, a watch is
unlikely at this time.
